Research on Algorithm Based-On the Fitting Algorithm of Subdivision Surface from Noising and Dense Triangular Meshes

Having studied the technology of triangle simplification in depth, for the shortcoming of big calculating amount and poor efficiency of QEM used in a fitting algorithm of subdivision surface from noising and dense triangular meshes, here applying a more optimization algorithm of mesh simplification based on local polynomial fitting to improve the original approach. Experiment had proved that the improvement had made sense.
